Synopsis Stability charts are presented to facilitate the computation of the factor of safety of earth slopes during rapid drawdown. As the reservoir level is lowered, the factor of safety decreases if it be assumed that no dissipation of pore pressure occurs during drawdown. Pore pressures during drawdown have been estimated by assuming that B is unity and stability calculation for the range of sections and soil parameters commonly encountered in earth dam practice have been carried out using an electronic computer in order to obtain the data given in the charts Des cartes de stabilité sont présentées pour faciliter le calcul du facteur de sérité des pentes en terre pendant un affaissement rapide. A mesure que le niveau du réservoir baisse, le facteur de sécurité diminue s'il est supposé qu'aucune disparition de la pression interstitielle n'a lieu pendant l'affaissement. L'évaluation de la pression inter-stitielle pendant l'affaissement a ét´ effectu´ en supposant que B est l'unite et les calculs de la stabilité pour la gamme des sections et les parametres relatifs au sol dont l´usaee est habitue1 dans les travaux ayant trait aux barrages en terre ont été exécutés en utilisant une machine á calculer électronique afin d'obtenir les donnés apparaissant sur les cartes.

... The main internal factors include the geomaterial properties, existing potential failure surfaces, and groundwater conditions (Preisig et al. 2016;Zhang et al. 2018;Liu et al. 2025), whereas the external factors comprise reservoir water level variation, rainfall, and other human activities (Leshchinsky et al. 2015;Song et al. 2018a;Wang et al. 2025;Yan et al. 2019). A rapid drop in reservoir water level generally decreases the slope stability surrounding the reservoirs, as Morgenstern (1963) and Aniskin et al. (2024) confirmed. Therefore, studying reservoir bank slope deformation and stability evolutions during rapid drawdown is particularly important. ...
